Printed circuit manufacturing process: screen printing machines

pcb board manufacturer

A printed circuit is a plate that makes it possible to electrically connect together a set of electronic components. We use it in most everyday household items, such as:

  • remote controls
  • computers
  • Printers
  • Calculators
  • radios, etc.

Basically, pcb board manufacturer construct it from epoxy resin or fiberglass, covered with a thin layer of copper and then with a photosensitive varnish.

Constitution of a printed circuit

In order to allow the engraving of the printed circuit, pcb board manufacturer uses a typon is used which is placed on the resin of the plate. The printed circuit can consist of one or more layers of copper, which, in this case, will be separated by an insulating film. The track of a printed circuit is a thin metal strip which serves as an electrical connection. Each track ends with a patch which is the conductive area of ​​the printed circuit.

Pcb board manufacturer Production process

During the artisanal creation of printed circuits, we use an insoleuse which allows to transfer the patterns drawn on the artwork, its printing on transparent paper, the exposure of the epoxy plate, its revelation, its engraving for which we use perchloride and which will be neutralized.

The cold tinning then makes it possible to treat the tracks while ensuring a protection of the copper as well as a better adhesion of the welds.

It is then necessary to drill in order to implant the various components of the printed circuit by soldering where the supplied metal consists of a mixture of tin (60%) and lead (40%). So as to obtain a eutectic mixture, within which the melting point will be less than 190 ° C. – Place the components and carry out the welds. – Finish with the varnishing of the circuits.

Other types of printed circuit

There are flexible printed circuits; pcb board manufacturer makes it using polyimide (PI) for example, due to the thermostability of the material. These flexible printed circuits will be mainly used in the manufacture of telephones, cameras, satellites, computer keyboards, etc. There are even ceramic printed circuits, used in the event of a particularly demanding thermal environment during certain military applications, or even space.

How does pcb board manufacturer create a prototype of pcb?

Manufacture of your PCB printed circuit prototype

We have the possibility to print small series of PCB plates according to your diagram or according to your GERBER file. We will use our CNC machine equipped with a javelin tip to engrave it. Of course, this is not the conventional method, but it will ensure immediate availability and the same assembly result. This method will allow us to see together the modifications made to your final file before being able to launch a final series via our supplier specialized in PCB.

PCB prototype

This is a solution for your prototypes in order to be able to test the feasibility of your printed circuit, moreover this method does not use any chemical product which makes it possible to reduce the ecological footprint.

3D printing and engraving at the service of companies

How did we get the idea to burn printed circuits? Simply thanks to pcb board manufacturer who are striving hard to meet he covid 19 challenges in industry. They are continuously providing their services ti the worldwide companies.


high-end PCB Manufacturers


Building a perfect electronics package begins with optimal circuit routing. In addition, the needs for the design of printed circuits have greatly increased in recent years: electronic parts are becoming more and more complex and compact, and must bring together ever more varied components.

For your electronics system, we create new circuit diagrams or optimize your current circuit design. Our approach depends on the most economical solution for you that guarantee the best quality for the manufacturing and assembly process.


Thanks to pcb board manufacturer, they are able to develop a new circuit board design or optimize your circuit. For the realization of the routing topology, we have diversified technologies and the most recent on an international scale:

  • Multilayer printed circuits (multilayer)
  • Starrflex PCBs, Flex PCBs
  • SMI Printed Circuits (Insulated Metal Substrates)
  • HDI Printed Circuit Boards (High Density Interconnect Circuits)
  • Thick Film Copper PCBs
  • Long printed circuits (longboards)
  • Ceramic substrates
  • Glass substrates
  • Bead matrix (BGA), chip-on-board (COB)
  • Integrated components

When pcb board manufacturer develop your printed circuit diagram, they also determine the most suitable shape for the printed circuit, the smallest possible miniaturization, high equipment density, thermal management and of course the measures necessary to ensure electromagnetic compatibility ( CEM).

The wasted energy burns as heat. This energy comes from a power station or a battery. And even worse, if the energy is burning inside a building, air conditioning burns even more energy to cool workers and machines. Less heat loss means better products too. As we engineers know, the best designs are also the most efficient.

How does the power supply of a printed circuit board work?

Once upon a time, a single logical power supply, such as + 5V, was often the only device power supply on a PCB. Not anymore, because:

  • FPGAs, IOTs, and many other devices support multiple (often configurable) IO standards and these require a variety of supply voltages
  • Many devices, including the DDR 3/4/5 SDRAM, have base supply voltages separate from their I / O supplies. DDR4 also needs a separate Wordline Boost power supply
  • More and more, analog and RF circuits share a PCB alongside digital. These power supplies require careful distribution as well as separate supply voltages
  • The end of bus termination, for example, Address / Command on DDR3, switches to an intermediate level termination voltage (VTT). It is not sufficient to divide the supply voltage with two resistors. This voltage must be stable – so yet another supply voltage

In many models you need a range of DC supply voltages. Usually you create them using DC-DC converters. Old-fashioned linear regulators aren’t really a good idea, except when the power they deliver is tiny. A linear regulator often has a large metal body.

This is because they “burn” a lot of wasted energy. A modern “Buck” regulator, on the other hand, is much more efficient – typically at least 80%. But Buck converters need a neat layout because, DC or not, they use high frequencies and are essential for layout. More efficient means less waste heat.

The idea of ​​a “low speed” and “high speed” separation is quite outdated, especially with the growth of the Internet of Things (IoT). We need to make sure that all the objects on a PCB work in harmony.

The process of route signals on high speed digital pcb board

The way we route signals on high speed digital boards works because we do it in a certain style: reference planes, differential pairs, impedance control. All of this shapes electric and magnetic fields so that we can predict how they will behave.

Digital signals are going really fast now, so fast that we have to treat it as a 3D problem from start to finish. This all applies to RF, because RF works outside of a lot of the assumptions we make for the rest. It can get weird. If you have wireless connectivity then you have RF.
